Answer 1

Answer:

Step-by-step explanation:

Q no 4 :

4, 8

1, 5

3, 7

2, 6

Q no 5:

(a)

10x + 1 = 12x - 5

1+5= 12x - 10x

2x = 6

x = 6/2

x = 3

(b)

11x - 15 + 5x - 13 = 180 (angles on a straight line)

11x + 5x - 15 - 13  =180

16x - 27 = 180

16x = 180 + 27

16x = 207

x = 207 / 16

x = 12.9375
